Services from Paris to Belfort are all booked loco and stock, along with a few odd shorter workings from Paris to Troyes / Culmont. I would recommend joinging the Yahoo group 'Eurpoean Rail Gen' (ERG) which has a files section containing loco diagrams by country - the most up to date SNCF ones are I think December 2012, but AFAIK are still accurate aside from minor timetable changes.
